One embodiment is shown in fig. 1-6.
The thickness control device for stainless steel cold rolling comprises a bottom plate 1 and two supports 2 which are fixed on the bottom plate 1 and are symmetrical to each other and are provided with a distance space, wherein a lower rolling shaft 3 is jointly installed at the bottoms of the two supports 2 through bearings, sliding rails 4 are downwards arranged along the tops of the two supports 2, sliding blocks 5 are arranged on the two supports 2 through the two sliding rails 4, an upper rolling shaft 6 corresponding to the upper portion of the lower rolling shaft 3 is jointly installed between the two sliding blocks 5 through bearings, a telescopic rod is installed at the top of one support 2 and is vertically downwards connected with the sliding blocks 5, and an electric cylinder 14 which is used for driving the sliding blocks 5 to drive the upper rolling shaft 6 to be close to or far away from the lower rolling shaft 3 is used for adjusting the distance between the upper rolling shaft 6 and the lower rolling shaft 3, steel plates with different thicknesses are rolled through rolling, and thickness control is carried out on hot-rolled steel plates when the hot-rolled steel plates are converted into cold-rolled steel. It can be seen that the upper roller 6 and the lower roller 3 together form a discharge mechanism for conveying the hot rolled steel sheet outward after rolling, the distance between the upper roller 6 and the lower roller 3 can be changed when the upper roller 6 moves downward, and thus the thickness of the hot rolled steel sheet can be changed when the hot rolled steel sheet is conveyed outward, and a motor 7 for driving the lower roller 3 to rotate and forcing the lower roller 3 to convey the hot steel sheet to the discharge side is fixed on one bracket 2, which is a general rail pressure mechanism, and the most important prominent point in the invention is that: the hot rolled steel is rolled through the lower roller 3 and is rolled together with the upper roller 6 to be conveyed outwards towards the discharging side, the upper roller 6 can rotate automatically, the first flapping mechanism 8 comprises upper arm rods 9 which are respectively arranged on the two sliding blocks 5, the upper spring 10 which is connected between the two upper arm rods 9 and is contacted with the upper surface of the cold rolled plate is further arranged on the first wheel disc 11, a first wheel disc 11 is arranged on the outer side of one bracket 2, the inner end of the first wheel disc 11 is provided with a synchronizing shaft 12 which penetrates through the bracket 2 and is connected with the upper roller 6 in a transmission mode, when the hot rolled steel rolls together with the upper roller 6 to be conveyed outwards towards the discharging side, the upper roller 6 can rotate automatically, and meanwhile, the first wheel disc 11 can be driven to rotate synchronously, and the first wheel disc 11 is further provided with a connecting rod mechanism 13 which is movably connected with the upper arm rods 9.
As can be seen from fig. 3, in order to improve the stability of the steel sheet during transport, a support wheel 15 for supporting the bottom surface of the cold-rolled sheet is also fixed to the bottom plate 1 on the feed side of the control device.
As shown in fig. 3, 4 and 6, a second beating mechanism 16 is arranged between the two sliding blocks 5 and positioned at the discharging end of the control device, the structure of the second beating mechanism 16 is identical to that of the first beating mechanism 8, wherein the second beating mechanism 16 also comprises a lower spring 17 which is identical to that of the upper spring 10 and is installed in the same way as the upper spring 10, unlike the first beating mechanism 8, the lower spring 17 in the second beating mechanism 16 corresponds to the discharging side of the control device, the upper spring 10 on the first beating mechanism 8 acts on the lower surface of the cold-rolled sheet during beating action, the upper spring 10 is positioned on the feeding side of the hot-rolled section of the steel sheet, the lower spring 17 is positioned on the discharging side of the steel sheet towards the cold-rolled section (close to cold rolling after rolling and cooling, continuously discharged into a deoxidizing layer in a pickling tank to become cold-rolled steel after being processed), it can be seen from the figure that the second wheel disc 18 with the same structural function as the first wheel disc 11 is installed on the bracket 2 on the opposite side of the first wheel disc 11 in the same installation manner, and is used for converting the rotation of the upper roller 6 into the flapping of the lower spring 17 on the lower surface of the cold-rolled plate, when the second wheel disc 18 rotates, the lower spring 17 is forced to tap the steel plate discharge end from the bottom by the same connecting rod driving principle like the first wheel disc 11, besides the rotation connection between the upper arm 9 and the sliding block 5, a bending spring is arranged between the upper arm 9 and the sliding block 5, so that the upper spring 10 frequently taps the upper surface of the steel plate under the continuous rotation of the upper roller 6 and the uninterrupted rotation of the first wheel disc 11 driven by the synchronous shaft 12, the lower spring 17 frequently taps the lower surface of the steel plate, particularly, on the discharging side, the carbon layer formed on the surface of the steel plate discharging section is enabled to fall off completely and downwards due to the fact that the carbon layer tends to fall off when the steel plate is rolled and discharged during hot rolling treatment, and after the finally discharged steel plate enters a subsequent phosphating pool for deoxidizing layer treatment into a cold-rolled steel plate, the surface quality (the high carbon content on the surface is pearlite and the color is blackened) cannot be influenced due to the fact that a large amount of carbon layer exists on the surface.
In order to increase the beating area, as shown in fig. 2, a plurality of steel balls 19 are also arranged on the upper spring 10 and the lower spring 17 along the length direction thereof.
In order to make the steel plate realize stability under the action of the supporting wheel 15 like the feeding end at the discharging end when being beaten, therefore, a limiting mechanism for preventing the steel plate from tilting upwards is required to be arranged at the discharging end, and the following steps are specifically: a side arm rod 20 extending towards the discharging side direction of the control device is fixed on one sliding block 5, a vertical downward falling rod 21 is fixed at the extending end of the side arm rod 20, a limiting rod 22 extending along the width direction of the side top surface of the cold-rolled sheet is arranged at the bottom end of the falling rod 21, the falling rod 21 is a hollow tube, a downward vertical channel 23 is formed in the tube cavity of the falling rod 21 facing the limiting rod 22 from the end surface of the falling rod 21, a spring rod 24 is welded in the tube cavity of the falling rod 21, an end rod 25 penetrating through the channel 23 and being in sliding fit with the spring rod 24 is arranged at the end of the limiting rod 22, namely, when the discharging end of a steel plate is knocked up and tilted upwards, the limiting rod 22 at the top can take the steel plate, vibration is reduced through compression buffering action performed in the hollow tube by the spring rod 24, and meanwhile tilting trend is limited.
The above-described embodiments are provided to further explain the objects, technical solutions, and advantageous effects of the present invention in detail. It should be understood that the foregoing is only illustrative of the present invention and is not intended to limit the scope of the present invention. It should be noted that any modifications, equivalent substitutions, improvements, etc. made by those skilled in the art without departing from the spirit and principles of the present invention are intended to be included in the scope of the present invention.
